Find me a case of another person being charged with purchasing a gun while being addicted to a drug. Or better yet tens of thousands. You might find someone arrested for attempting to buy a gun while on drugs, but none that reviewed their past logs and tried to find out they were possibly addicted at the time of a purchase of a gun.

It was an investigation that I've never seen anywhere before. Any normal situation and a judge would have dismissed it completely as the person was not on drugs at the time of the charge, nor harmed/threatened anyone with the gun

Note: several judges stated such laws were unconstitutional during the years of the investigation, so any Republican supporting it must admit that States have the right to restrict any and all gun purchases for any and all reasons as the constitution states no such laws pertaining to addiction over lap and gun purchases... Or the law cannot support that case

Sidebar: whatever he did with taxes if it was unlawful and others do get charged with it, sure he should be charged
